NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 394,097, dated December4. 1888.

Application filed June 19, 1888. Serial No. 277,564. (No model.)

To all 207mm it may CON/06771:

Be it known that I, JAMES I). CLEEK, a citi- Zen of the Enited States,and a resident of Abingdon, in the county of \Vashington and State ofVirginia, have invented certain new and useful Improvements inNut-Locks; and

I do declare the following to be a full, clear,

and exact description of the ii'ivention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure l of the drawings is a representation of this invention and is avertical section. Fig. 2 is a vertical section taken where the brokenline .1 is marked on Fig. 1. Fig. 2-3

is a detail showing the under side of the nut. Figs. r, 5, ti, and T aredetails.

This invention has relation to devices for locking bolts and nuts; andit consists in the construction and novel combination of devices, ashereinat'ter set forth.

In the acctnnpanying drawings the letter A designates a bolt, and 1- anut thereon.

( designates a *tish-plate or other bearing,

which may have a slight depression at g.

The bolt A is tornu-a'l with a longitudinal 3o groove, I), along itsthreaded portion, said groove being shallow and having suiiicientbreadth to receive a key, E, which is thin enough to be seated in thegroove within the sweep of the thread, so that the nut B can be turnedhome when the key is in position.

F is a washer having a central opening for the passage of the bolt andthe rectangular olt'sets 72. 71. to said opening, forming lockingnotchesfor the outwardly-extended foot is of the key. This font 7.: is bent atright angles to the shank of the key and serves to hold the bolt andwasher in relative position.

The nut B at its outer end is provided around the opening with thesloping ratchet- .notches I, said notches extending outward at an obtuseangle from the threaded portion of the opening, as shown. At its innerend or bar the nut may be formed an annular recess or cl'iamber, n1,around the central threaded opening of sutfieient dimensions to receivethe foot of the keywhen desired.

Before applying the nut the key is laid in the groove of the bolt, withits foot engzlging one of the notches ot' the washer and the depressiong of the bearing. The nut having then been turned home, the end of thekey which projects outward beyond the nut is bent to one side, so thatit will engage one of the ratehets ot' the nut. The key is also easilyrestored to its normal straight shape when it is desired to remove thenut. In order to turn thenut without straightening the keyas, forinstance, when it merely needs setting up or loosening-the key can bemoved outward a little, bringing its foot into the recess in, when thenut will turn freely.

Having described this invention, what I claim, and desire to secure byLetters Patent, is

In a nut-lock, the combination of the grooved 7o bolt, the key adaptedto fit in said groove and having the outwa rdly-turned foot, the nuthaving the ontwardly-sloping ratehet-notches around the outer end of thethreaded opening and the annular recess around the inner end of saidopening, and the notched washer, all as shown and described.

In testimony whereof I atlix my signature in presence of two witnesses.
